Addressing Grid Reference for King County

Provides the street number corresponding to various State Plane based linear features (section lines mainly) according to the address grid as defined by code for unincorporated King County. Quarter-section lines were added to cover most of the County outside of the Forest Protection district. The City of Seattle address grid is represented in this layer, but is not considered authoritative. Any other cities in King County that have alternate addressing grids are not currently represented in this layer. Including alternate addressing grids in the portions of King County where they are used is a planned enhancement for this layer.
